Metals Processing

Annealing

Air Products offers a variety of technical services, gas-based solutions and a full line of industrial gases—including nitrogen, hydrogen and various gas blends for small and large volume users. Our applications engineers can work with you to understand your annealing process and recommend improvements that can help you optimise gas use and improve product quality.

Gas atmospheres for annealing can range from nitrogen-based blends with hydrogen for carbon steels (to improve microstructure, surface appearance and reduce residual stresses), to 100% hydrogen (for stainless steels or for faster batch processing of carbon steel components). For vacuum annealing of reactive metals, we can provide argon or helium atmospheres. Our atmospheres can help you achieve improved and consistent part quality, reduced post-heat-treatment cleaning or pickling costs and reduced furnace maintenance.

Analytical Panels

These panels allow you to measure hydrogen, moisture, oxygen, carbon dioxide and hydrocarbon concentrations in furnace atmospheres for real-time monitoring and control of your furnace parameters. This information can help you improve operational consistency, flexibility, quality and safety.

Atmosphere Recycling and Purification Systems

Air Products can evaluate your operations to provide recommendations regarding the benefits of recycling and purification systems. In addition, Air Products can design and build a customised system to meet your needs.

Nitrogen Supply Monitoring Systems

Our nitrogen supply monitoring system can help you improve process safety related to embrittlement of carbon steel components. The system monitors nitrogen supply parameters, such as storage tank level, pressure and nitrogen house-line temperature to provide operators with an alarm if the levels fall below desired settings.

Process Control and Monitoring System

Our advanced monitoring and control system allows you to continuously monitor and regulate the true oxidising/reducing potential of the atmosphere, as well as track, record and organise process data for your annealing operation. This information can help you achieve consistent and reliable product quality, reduced re-work or defects and improved process safety.

Audit Services/Leak Detection

Our applications engineers can work with your plant personnel to analyse and understand your entire process. Based on that analysis and your needs, they can recommend process improvement solutions that can help you enhance product quality and consistency, plus optimise gas use. Air Products' services include leak-checking, furnace profiling, analytical calibration, gas analysis process troubleshooting and overall process review.

Training

Training can include gas atmosphere safety, properties of gases, metal treating applications, NFPA 86, piping and flow control panel requirements and troubleshooting for atmosphere problems. This information can help keep your furnace operations safe and help prevent accidents.
